CONVEYER MECHANISM.

Application filed March 12, 1919. Serial No. 282,094; I

To all whom it may concern:

Be it known that I, RICHARD S, JACOBSEN,

a subject of the King .of Norway, residing in 1 the city of Chicago, in the county of Cook 5 and State of Illinois, have invented new and useful Improvements inConvey'er Mechanlsms, of which the following is a specifica: tion.

This invention relates to improvements in by actuating a plurality of conveyers and a' filler for one of said conveyers from a common shaft.

Another object of the invention is to provide a drive for reciprocating conveyers and 4 a filler wherein the rate of speed at which the conveyer receptacles and the filler move at different points of their travelvaries.

It is also an object of the invention to provide a combination of conveyer recepsorting operationof the material conveyed, one or several of the conveyer receptacles having extensions in which waste material may be conveyed to points different from that to which the valuable product is conveyed. 7

With .these and other objects in view, an embodiment of the invention is illustrated in the accompanying drawing and is described in the following specification.

In the drawings Fig. 1 is a side elevation and partly section through a conveyer mechanism of this kind 1 2 is a top plan View of a conveyer plant: Y

I on line H of Fig. 2, illustrating'the. mounting of the eccentrics.

The drive shaft 1, through the rotation of which reciprocating movement is-imparted to the conveyer receptacles, is supported in outer bearings (diagrammaticallyindicated at 2), and in inner bearings 3, which are mounted upon a suitable foundation 4. 1

These inner bearings are provided. with an eccentric portion 5, on which a pulley 6 rotates. This pulley is driven at a uniform 1 rate of speed about an axis eccentric to, that of the drive shaft 1, and the uniform rotation of the pulley ,is communicated to the shaft lby means of a link 7 attached at one; end to the'pulley and at the other endto-a crank arm 8, which is rigidly mounted on the drive shaftl Owing'to this arm and link connection between pulley and drive shaft, the uniform rotation of the pulley is converted into a non-uniform rotation of thedrive shaft. A prime mover, shown here in the form of an electric motor 9, carries a small pulley 10, from which, through belt transmission, a pulley '11 on a countershaft 12 is driven. The rotation of the shaft 12 takes place at a speed lower than the" speed of the pulley 10, and a second reduction of I including the pulley 13 on the countershaft 12 and the belt 14, which is trained about the Two conveyerreceptacles, 15;and 16 respectivelyfreceive reciprocating movement from the drive shaft 1, which,- -as stated -above,is' rotated at anon-uniform rateof speed. The means for actuating the conveyer receptacles 15 and 16 comprises eccen mannerthat the movement of the conveyer 15 in one direction coincides with the move-,

ment of the conveyer receptacle 16in the opposite direction. The connection between the eccentricsw17 with. the conveyer receptacle .15 :is established by means of co nnect-v ing rods 19, secured to the eccentric 17 at one end and at the other end to av rod oraxle 20, which is supported on the lower side of j the conveyer receptacle15. The outer ends of this axle carry rollers 21, which ride upon a suitable support 22, and similar} rollers also are used for supporting the'remotefe nd of the upper conveyerreceptacle15. 7

having their-wends secured to a transverse bar 24, which is mounted inbrackets 25 on the lower receptacle. This lowerre'ceptacle' is supported on rollers 26, which ride on a suitable foundation 27, and which are interconnected by a bar 28,:zalthougha llglCl' connection .oi this bar with the lower recepta cle is not necessary. The remote end of" the lower receptacle 16 may he supported by similar rollers.

I @The construction oi the conveyermecha n'1smas described does not form the pr'e ent invention, noris any claim directed to the connection "of the eccentrics with the shaft. A detail of this connection is'illustrated in Fig. 4;1wl1erein the shaft 1 is sur- 0 rounded by an eccentricvdisk 17 on which a two-part eccentric ring li' is adjustably mounted. A variation of the tlHOW lS'IflP dered' possible owing to the provision-oi a.

F plurality of notche'sitl in the circumference ZS'of the' eccentric dish 1'2". which may be brought into registration with a'not'ch 32in" the eccentric ring 17"". Art'er suitable rela tive adjustmentot the eccentric 'di'slrand-the ring, the 'parts'may held adjusted ret 301'? lation through the-insertion or aloching'pin 33 "into the registering notches.

' Thein'aterial is supplied to the 'onveyer receptacle l-5 through a spout 3d, the lower I end of which has lateral walls 35 to confine the discharge opening. A'ngle' irons 36, mounted on theSu-rfac'e or these lateral walls carry brackets 37, in the lower ends of which the rollers 88 are mounted. These-rollers serve for isupporting a trough or filler 39, which forms a movable bottom" closure for the spout, and which is I'C1PIO-' cated to gradually transfer the charge poured into the spout 34L into theuppeifr ceptacleli. The actuation o' this tiller 39 c; cii ected' from supportedby; the rollers 38' 7' the common drummer hy incans'ot eccen trics a0,"\vliicli are connectedthrough the" rods etl with a trziusverso baif'lQ, supported at'the inner end otthe filler 39. As shown 5077' ii tlie drawing (Fig; l) the ccentrics 40 have approfiimately the saiuo relation to the the lower conveyer eccentrics 1'8 actua't I receptacle 16 asthc eccentrics 17 to the upper receptacle 15, altheugh thisis not essential.

"* lt s obvious that through suitable angular ad ustment I the 'eccentrics 120 the .iilleiqgtl may be advanced indirect on towards thii upper recept cle.'15 'at the/sa ne time which said'upper receptacle is advanced in p direc 11' towards the tiller 39; so that the e; t to elements (the upperflconveyerreceptacle" tic. e The upper veyer receptacle tepid;

Lateral dispersion of the material dropping through, the bottom 431m; prevented owing to the provision of shirts 4:5 which are fastened vto the lower edge of the upper receptacle "15, and which contverge, as shown in 3, towards the (zentral portion l l of the lower receptacle For the purpose of facilitating theassort'-'- ment of thatmaterial which has not eecn reen'ed in the upper conveyer and disl charged at the point C oi the lower conveyer, the following structure is provided! Brackets 46, attached to the upper receptacle 15' near the rear end 01": the perforated bot-Q tor-n43; support centrally above said'conveyor 15 a trough 4:7, to which; owing to this rigid COl11'lGCtlO11,-tlfl8 sam'emoveinent is in; parted which is imparted to the upper ever, is provided withlongitudinal partiti walls 48 and with lateral walls d9, whereby at both sides of the central portion" it cha n; n'els 50"are'formed; to which movement is imparted in' the same direction as to the" lowerrec'eptacle 16. The trough 47.,aswell as the channels 50, may serve for conveying additional material to differentpoints'ot the plant; the material depositedin the trough: i? being conveyed in the dircctioii' c-E-the mow, while the material carried in the channels 50 will be discharged at the poin E inthe direction of. the arrow indicated. The operation oi the conveyer mechag' IllSIl'l' as,';to1- instance, used for conveying coal from a mine may he described asftol'5 ows we i I .f 'The'mine run coal is poured-[into th' spout 34-, from whichjit is transferred-fow ing to the action-ofthe filler 39,'to theupper receptacle 15.

Picker boys are stationednear in direction of the arrow Ate the rear end of the receptacle 15 The mine run, how- 7 ever, is not only formed of large and small lumps oit' valuable material, but it usually also contains material of less value (socalled bone coal) and material of no value (slate), which cannot be used. The picker boys will remove the lumps of ma-v terial from the rear portion of the upper conveyer 15 and throw the bone coal, for instance, into the upper trough 47, which conveys the same to a point of dischargein the direction of the arrow 13, while slate, stones, sulphur may be thrown by the picker boys into the compartments 50 of the lower receptacle 16, to be discharged at the forward end of these channels near the point E.
